A little bit of knowledge can save you big money with repair bills, whether you plan on doing the repair yourself or if a professional contractor will have to be called in. With proper advance planning and preparation, you can keep a malfunction from becoming a major and costly damage crisis.
Electrical
Know the location of the shutoffs for the home electricity. Make sure the circuit breakers or fuses are all appropriately marked and that the identifiers can easily be read by the light of even a dim flashlight.
Just because you have shut off the electricity to a room or appliance, don’t assume that there is no voltage to the appliance or outlet. Check and double check to make sure that there is no electricity running through to avoid property damage or injury. Use a voltage tester to make sure you won’t get an unexpected shock.
Gas
Locate the main shut off valve for the gas line into your home. Make sure every family member knows the location. Make sure you are familiar with how the valve works. In an emergency like a leak, shut off the outside main valve first to keep leakage to a minimum. Once the main line has been closed, you will have the time to access the shutoff valve for the appliance without being overcome by fumes.
Water
A broken water line can quickly cause a lot of damage. Most sinks and toilets, as well as electrical appliances that use water have a shutoff valve in the vicinity of the fixture. But it’s always important to know where the main shut off valve is located in case the damaged water line or pipe is spewing water before it gets to the shutoff valve.
